Dairy Husbandry Department
With a view of testing the practicability of the milking machine, the South Dakota experiment station, two years ago last February, installed the Hazelwood milking machines in the college dairy barn. These machines, with the exception of one day out of each month when the machine milked cows were milked by hand, and also in a few instances when the gasoline, engine used for power underwent repairs, have been in continuous operation since that time, or for nearly two and one-half years. The cows were milked by hand one day of each month to ascertain the approximate production of individual cows. The Hazelwood machine milks two cows at a time, and has no partition in the pail. Two machines were installed, as one man can attend to two as well as to one. The data on hand at the present time are not complete, but on account of the demand for information regarding milking machines, this preliminary report giving the results to date with this particular make of milking machine is issued.
